To all whom it may concern.'.

Be it known that I, SIMON KORPER, a citizen ofthe United States of America, residing at New York, in the borough of Manhattan,

countyand'State ofNcw- York, have invented certain new and useful Improvements in Safety-Razors, of which the followperforations teeth a and at the mg 1s a specification.

This invention relates to an improved safety-razor of that class in which the razorblade is sharpened at opposite edges and adapted to be used for shaving with either edge by reversing the frame, but without reversing the blade itself; and the invention consists of a safety-razor the frame of which is provided with guard teeth at o posite sides and at the ends with means for Folding a blade sha ened at both sideedges in position on the rame, said frame being provided with a short shank having locking pins that are introduced into the doubled-up shank of the holder, said shank being provided with receiving the pins and with outwardly-bent ends for ermitting the insertion of the shank of the razonframe. The end of the shank of the razor-frame is made V-shaped so that either one or the other of the inclined edges fits against the back of the holder-shank, and reversiblyholds the. frame in a predetermined inclined position so as to permit the use of either e ge of the lade. i

In the accompanying drawing, Figure 1 represents a front-elevation of my improved safety-razor, Fig. 2 is a rear-elevation of the same, Fig. 3 is a longitudinal section on line 3, 3, Fig. 1, drawn on a larger scale, Fig. 4 is a transverse section on line 4, 4, Fig. 1,. and Fig] 5 is a detail transverse section on line 5, 5, ig. 4.

Similar letters of reference indicate corres onding parts.

eferring to the drawing, a represents the frame of my im roved safety-razor. The frame is provide at both sides with guardfour corners of the frame with raised corner-pieces a that hold a blade b in position agalnst pressure on the other edge. Thebladeb is rovided with sha ened edges at both sid gs and is retained in osition on the frame a by an overhanging ug d at one side of the frame and a swiveled lug'orflcatch d at the opposite side, so that by turning the catch d 'sidewise the blade turned over the op as to hold the bla can be readily removed from the frame for cleaning or 'resharpening. When the blade is placed in position again under the lug (l and within the cornerepieces a osite edge of the blade so e firmly in position in the frame for shaving.

The frame is provided With a shank e that extends at right angles to the body-of the frame and is formed by doubling up the stock that is-punched up from'the body of the frame and lacing the shank -pieces alon side-of eacli other. The end of the shan is made V-shaped,1the angle formed by the V being rectangular, as shown in Fig. 3. The shank .is provided at each side in line with the apex of the angle with a short bent-up projection e which can be readily inserted into the shank f 1 of a holderf. The shankj is of U-shaped'cro'ss-section and open at the'front and top edges, the upper front corners being bent in outward dlrection so as to facilitate the insertion of the locking pins or projections between the opposite side-walls of the shank gaged by holes 0 in the shank, as shown in 3. In this osition one inclined edge 0 the V- haped s ank of the frame a abuts against the back of to hold the frame firml in a predetermined inclined position in sai .shank and thuspermit shaving with the lower edge of the razor. When the edge becomes dull the blade is not removed. for sharpening, but the frame removed from the holder by movingit in upward direction so as to permit the detaching of the shank of the frame from the shank of the holder. The frame is then reversed and the shank of the frame inserted into the doubled-up shank of the holder until the locking pins are sprung into the holes of the shank.

he op osite Inclined edge of the shank e abuts t on against the backof the shank of the holder so as to again lock the razor-frame in rigid osition. The opposite sharp edge of the b ade is now at the-lower end of the frame and used for shaving until it has also become dull. The blade is then removed from the holder and shar cried and then reinserted, bein then used first at one edge and then at t e opposite edge as described.

By my invention a safety-razor of very simple-and yet effective construction is obtained, in which theblade is not reversed for the catch al isthe holder-shank f so as until the pins are ena and with which it is detachably inter front and top edges shaving with the opposite edge, but the frame of the same reversed, said frame being su orted in either position of the blade by t e mterlockin-g connection of the shank of the frame with the shank of the holder.

Having thus described my invention, -I claim as new and desire to secure by Letters Patent:

1. A safety-razor comprising a blade-holding frame, a shank on said frame, a holdershank of U-sha ed cross-section open at the front and top e ges, and means to rigidly but detachably secure the frame-shank within the u )per end of theholder shank.

2. ln a safety-razor, a blade-holding frame having a shank, a holder-shank comprising opposite side-walls of. sheet-metal between which the frame-shank is sprung into interlocked relation with said holder-shank, and means to hold the frame-shank rigidly in in- ,clined position with respect to'the holdershank.

3. A safety-razor comprising a blade-holding frame, a shank made of portions bent u from the frame and extending alongside eac other, and a holder-shank of U-shaped crosssection within which said portions fit and with which they detachabl'y interlock.

'4. A safety-razor comprising a blade-holding frame, a shank extending therefrom, and

a holder-sh ank having opposite side-walls between which said first-named shank is laced ocked in an inclined position, said holder-shank being of U-shaped cross-section and 0 en at the for the insertion of the shank of the blade-holding frame.

extending alongside each other,

5. In a safety-razor, the combination of a blade-holding frame, a shank on said frame composed of portions formed of sprin metal and a ioldershank embodying opposite side-walls between which said portions of the frameshank enter, and into interlocking relation with which said portions are sprung.

6. A safety-razor comprising a blade: holding frame having thereon aframe-shank having rear edges disposed at an angle to each other, a U-shaped holder-shank comprising resilient side-walls and a connecting wall, and means carried by said frame-shank ada ted to be yieldably held by said side wal s to hold said frame-shank between said I side-walls and one of said rear-edges against said connecting wall.

7. A safety-razor comprising a bladeholding frame having thereon a frame-shank provided with oppositely extending rojections and having real edges dis oser at an angle to each other, a holder-s iank of U- shaped transverse section comprising a connecting wall and resilient side-walls having opposed holes, said projections being adapte to'engage said holes and ieldably hold said frame-shank between sairl side-wall and any oneilof said rear edges against said connecting wa In testimony, that I claim the foregoing as 'my invention, I have signed my name in presence of two subscribing witnesses.
